SOUNDING-LEAD.

SPECIFICATION forming part of Letters Patent No. 398,396, dated February 2 6, 1889. Application filed July 7, 1888. Serial No. 279,285. (No model.)

T0 aZZ whom, it may concern:

Be it known that 1, HORACE" HOLDEN, of East Orange, Essex county, State of NewJersey, have invented a new and Improved Sounding-Lead, of which the following is a specifil cation.

This invention relates to a sounding-lead for mariners use, which is so constructed that the ground taken. up by the arming will be protected while being drawn upward through the Water. Thus the ground will not be apt to be partly or entirely washed away before it reaches the surface.

The invention consists in the various fea tures of improvement more fully pointed out In the accompanying drawings, Figure 1 is a side view of my improved sounding-lead, showing the sleeve down. Fig. 2 is a vertical longitudinal central section of Fig. 1. Fig. 3 is a similar section as Fig. 2, but with the sleeve up.

The letter (i represents a sounding-lead ot' cavity in its bottom to receive the arming Z), as usual. Around the lead a. there is placed a sleeve, d, open at top and bottom, and having preferably a ttai'lge, e, at its upper end.

The sleeve (I is tree to slide up and down on lead 0.. Its upward motion is limited by l screws or stops f, projecting laterally from the lead a. The downward motion of the sleeve d is limited by the flange e, when closel; embracing the conical. body of the lead a, or by a laterally-projecting flange, g, at the bottom of the lead.

The operation of the device is as follows: I The lead, being dropped, will pass swiftly,

through the water so that the resistance of the water acting against the lower edge of the sleeve (Z will force the same upward until its flange e strikes against the stopsf. The sleeve is of such alength only that in this position l the cavity, with its arming I) will be exposed,

Fig. 3, so that as the lead strikes the ground the latter can come in contact with and adhere to the arming The lead being next raised, the gravity of the sleeve, together With the pressure of the water 011 its upper edge, will cause it to drop down into the position shown in Fig. 2, so as to project beneath the base of the lead. Thus the arming and ground will be protected against all currents,

and the ground may thus be raised to the surface without being washed away.

\Vhat I claim is- 1. The combination of a sounding-lead having a cavity in its base for the reception of.the arming with a sliding sleeve surrounding the lead and adapted to be projected beyond its base, substantially as specified.

2. The combination of a conical soundinglead with a sleeve embracing said lead and having flange 6, and with the stop f, substantially as specified.

5. The combination of a sounding-lead, a, with a surrounding sleeve, (1, having flange e, and with the stop f above sleeve (1, and with the laterally-projecting flange g at the lower end of the lead a, substantially as speci fled.
